Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve core technology, and in particular to a valve core structure that is easy to disassemble and maintain. Background Technology
[0002] Valve cores are mostly made of wear-resistant and corrosion-resistant materials such as ceramics and stainless steel. They come in various shapes, such as spherical and plunger shapes. During operation, the valve core position is adjusted by the valve stem to precisely adjust the valve opening, thereby controlling the flow rate, pressure, and direction of fluids such as water, gas, and oil.
[0003] The above-mentioned and existing technologies have the following drawbacks: When repairing the valve core, the bolts need to be removed before the valve core can be disassembled. After maintaining the valve core, the valve stem of the valve core is connected to the external operating handle with the bolts. During this process, the operator's view will be obstructed after the handle is put on the valve stem, making it difficult for the operator to align the bolt with the threaded hole on the surface of the valve stem, thus making it inconvenient to disassemble and maintain the valve core.
[0004] Therefore, a valve core structure that is easy to disassemble and maintain is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the handle, when placed on the valve stem, obstructs the operator's view, making it difficult for the operator to align the bolt with the threaded hole on the valve stem surface, thus making it inconvenient to disassemble and maintain the valve core. Therefore, this utility model proposes a valve core structure that is easy to disassemble and maintain.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a valve core structure that is easy to disassemble and maintain, comprising a valve core body, a valve stem rotatably connected within the valve core body, an adjustment groove being formed on the surface of the valve stem, an adjustment rod being slidably connected to the inner wall of the adjustment groove, an extension rod being fixedly connected to one end of the adjustment rod, a threaded hole being formed on the surface of the extension rod, a groove being formed on the surface of the extension rod, the groove communicating with the threaded hole, and the vertical cross-section of the groove being trapezoidal.
[0007] The aforementioned components achieve the following effect: through the cooperation of components such as adjusting groove, adjusting rod, extension rod and groove, the bolts can be easily removed when maintaining the valve core body, and can be easily installed after maintenance, thus facilitating the disassembly and maintenance of the valve core body.
[0008] Preferably, a guide block is fixedly mounted on the surface of the extension rod, and the vertical cross-section of the guide block is trapezoidal.
[0009] The effect achieved by the above components is that the guide block can guide the handle, making it easy to put the handle onto the extension rod.
[0010] Preferably, the valve stem is internally threaded with a screw, which passes through the valve stem and abuts against the surface of the adjusting rod.
[0011] The effect achieved by the above components is that after the screw abuts against the surface of the adjusting rod, it restricts the position of the adjusting rod, thereby restricting the position of the extension rod.
[0012] Preferably, the adjusting rod has a regular hexagonal prism structure.
[0013] The effect achieved by the above components is that the adjusting rod, which has a regular hexagonal prism structure, can restrict the movement path of the extension rod.
[0014] Preferably, the valve stem has a groove on its surface, the groove is connected to the adjusting groove, and a limit block is fixedly mounted on the surface of the adjusting rod, the groove and the limit block are slidably connected.
[0015] The effect achieved by the above components is that the adjusting rod will drive the limiting block to slide along the inner wall of the limiting groove, and the cooperation between the limiting block and the limiting groove can prevent the adjusting rod from coming off the inner wall of the adjusting groove.
[0016] Preferably, the surface of the adjusting rod is provided with a plurality of scale grooves.
[0017] The effect achieved by the above components is that the scale groove allows for convenient and precise adjustment of the position of the extension rod.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this utility model, the adjustment groove, adjustment rod, extension rod and groove and other components work together to facilitate the removal of bolts when maintaining the valve core body, and the bolts can be easily installed after maintenance, thus facilitating the disassembly and maintenance of the valve core body.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0028] like Figures 1-5 As shown, this utility model provides a valve core structure that is easy to disassemble and maintain, including a valve core body 1, a valve stem 2 rotatably connected inside the valve core body 1, an adjustment groove 3 on the surface of the valve stem 2, an adjustment rod 4 slidably connected to the inner wall of the adjustment groove 3, an extension rod 5 fixedly connected to one end of the adjustment rod 4, a threaded hole 6 on the surface of the extension rod 5, and a groove 9 on the surface of the extension rod 5, the groove 9 communicating with the threaded hole 6, the vertical cross section of the groove 9 being trapezoidal. Through the cooperation of the adjustment groove 3, the adjustment rod 4, the extension rod 5 and the groove 9, the bolts can be easily removed when maintaining the valve core body 1, and can be easily installed after maintenance, thus facilitating the disassembly and maintenance of the valve core body 1. A guide block 8 is fixedly mounted on the surface of the extension rod 5, the vertical cross section of the guide block 8 being trapezoidal, the guide block 8 can guide the handle, making it easy to put the handle on the extension rod 5.
[0029] A screw 7 is internally threaded onto the valve stem 2. The screw 7 passes through the valve stem 2 and abuts against the surface of the adjusting rod 4. After the screw 7 abuts against the surface of the adjusting rod 4, it restricts the position of the adjusting rod 4, thereby restricting the position of the extension rod 5. The adjusting rod 4 has a regular hexagonal prism structure, which can restrict the movement path of the extension rod 5. A groove 9 is formed on the surface of the valve stem 2. The groove 9 is connected to the adjusting groove 3. A limit block 11 is fixedly mounted on the surface of the adjusting rod 4. The groove 9 and the limit block 11 are slidably connected. The adjusting rod 4 will drive the limit block 11 to slide along the inner wall of the limit groove 10. The cooperation between the limit block 11 and the limit groove 10 can prevent the adjusting rod 4 from coming off the inner wall of the adjusting groove 3. Several scale grooves 12 are formed on the surface of the adjusting rod 4. The scale grooves 12 can conveniently and accurately adjust the position of the extension rod 5.
[0030] The overall working principle is as follows: When maintenance is required on the valve core body 1, the bolt is removed from the threaded hole 6, separating the handle from the extension rod 5. The valve core body 1 is then removed for maintenance. After maintenance, the valve core body 1 is placed back into the valve pipeline. Next, the handle is placed on the extension rod 5. During this process, the guide block 8 guides the handle, making it easy to place it on the extension rod 5. Then, the bolt is passed through the handle, and the bolt rests against the inner wall of the groove 9. The trapezoidal groove 9 guides the bolt, facilitating alignment with the threaded hole 6. This allows for tightening the bolt even when visibility is obstructed, improving maintenance convenience. When the position of the extension rod 5 needs adjustment, the screw 7 is rotated. The screw 7 will disengage from the adjusting rod 4 by moving along the thread, and then pull the extension rod 5 to adjust its position, so that the extension rod 5 can be connected with handles of different specifications. After adjustment, the screw 7 is rotated in the opposite direction. After the screw 7 abuts against the surface of the adjusting rod 4, it will restrict the position of the adjusting rod 4, thereby restricting the position of the extension rod 5. During the movement of the adjusting rod 4, the adjusting rod 4 will drive the limiting block 11 to slide along the inner wall of the limiting groove 10. The limiting block 11 and the limiting groove 10 cooperate to prevent the adjusting rod 4 from coming off the inner wall of the adjusting groove 3. At the same time, the scale groove 12 can conveniently and accurately adjust the position of the extension rod 5. The adjusting rod 4, which has a regular hexagonal prism structure, can restrict the movement path of the extension rod 5.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
